New approach for time-resolved and dynamic investigations on nanoparticles agglomeration

Anaraki, Neda Iranpour ; Sadeghpour, Amin ; Iranshahi, Kamran ; Toncelli, Claudio ; Cendrowska, Urszula ; Stellacci, Francesco ; Dommann, Alex ; Wick, Peter ; Neels, Antonia

In: Nano Research, 2020, vol. 13, no. 10, p. 2847–2856

Nanoparticle (NP) colloidal stability plays a crucial role in biomedical application not only for human and environmental safety but also for NP efficiency and functionality. NP agglomeration is considered as a possible process in monodispersed NP colloidal solutions, which drastically affects colloidal stability. This process is triggered by changes in the physicochemical properties of the...

Design and characterization of bio-inspired antimicrobial nanomaterials

Zabara, Mahsa ; Hong, Linda ; Salentinig, Stefan

In: CHIMIA International Journal for Chemistry, 2020, vol. 74, no. 9, p. 674–680

Colloidal structures are crucial components in biological systems and provide a vivid and seemingly infinite source of inspiration for the design of functional bio-inspired materials. They form multi-dimensional confinements and shape living matter, and transport and protect bioactive molecules in harsh biological environments such as the stomach. Recently, colloidal nanostructures based on...

Inverting structures: from micelles via emulsions to internally self-assembled water and oil continuous nanocarriers

Glatter, Otto ; Salentinig, Stefan

In: Current Opinion in Colloid & Interface Science, 2020, vol. 49, p. 82–93

Fluid-like colloidal structures are key components in nature's own functional materials and important for various applications. For instance, self-assembled structures are formed spontaneously by amphiphilic molecules in solvent, tailored by directional noncovalent intermolecular forces. These structures form the framework of cells defining their geometry and microenvironments for chemical...

Responsive nanofibers with embedded hierarchical lipid self-assemblies

Tien, Nguyen D. ; Maurya, Anjani K. ; Fortunato, Giuseppino ; Rottmar, Markus ; Zboray, Robert ; Erni, Rolf ; Dommann, Alex ; Rossi, René M. ; Neels, Antonia ; Sadeghpour, Amin

In: Langmuir, 2020, vol. 36, no. 40, p. 11787–11797

We introduce the design and study of a hybrid electrospun membrane with a dedicated nanoscale structural hierarchy for controlled functions in the biomedical domain. The hybrid system comprises submicrometer-sized internally self-assembled lipid nanoparticles (ISAsomes or mesosomes) embedded into the electrospun membrane with a nanofibrous polymer network. The internal structure of ISAsomes, ...

Nanostructure generation during milk digestion in presence of a cell culture model simulating the small intestine

Hempt, Claudia ; Gontsarik, Mark ; Buerki-Thurnherr, Tina ; Hirsch, Cordula ; Salentinig, Stefan

In: Journal of Colloid and Interface Science, 2020, vol. 574, p. 430–440

Hypothesis: The development of advanced oral delivery systems for bioactive compounds requires the fundamental understanding of the digestion process within the gastrointestinal tract. Towards this goal, dynamic invitro digestion models, capable of characterising the molecular as well as colloidal aspects of food, together with their biological interactions with relevant invitro cell culture...

Self-assembly of glycerol monooleate with the antimicrobial peptide LL-37: a molecular dynamics study

Innocenti Malini, R. ; Zabara, M. ; Gontsarik, M. ; Maniura-Weber, K. ; Rossi, R. M. ; Spano, F. ; Salentinig, Stefan.

In: RSC Advances, 2020, vol. 10, no. 14, p. 8291–8302

Over the past decade, the rapid increase in the incidence of antibiotic-resistant bacteria has promoted research towards alternative therapeutics such as antimicrobial peptides (AMPs), but their biodegradability limits their application. Encapsulation into nanocarriers based on the self-assembly of surfactant-like lipids is emerging as a promising strategy for the improvement of AMPs'...

Colloidal transformations in ms2 virus particles: driven by ph, influenced by natural organic matter

Watts, Samuel ; Julian, Timothy R. ; Maniura-Weber, Katharina ; Graule, Thomas ; Salentinig, Stefan

In: ACS Nano, 2020, vol. 14, no. 2, p. 1879–1887

Enteric viruses, such as enterovirus, norovirus, and rotavirus, are among the leading causes of disease outbreaks due to contaminated drinking and recreational water. Viruses are difficult to remove from water through filtration based on physical size exclusion—for example by gravity-driven filters—due to their nanoscale size. To understand virus removal in drinking water treatment ...
